mapping nested beans to multiple lines in a file! #437

Closed niksrivastav closed 3 years ago

niksrivastav commented 3 years ago

i am working in a camel project where i have a .DAT file from which i am trying to populate my data in my nested beans and then after some changes from populated beans i am trying to generate a file which have data present in those beans.

my POJO's are like:

class POJO1{
field a;
field b;
list<class POJO2>;
list<class POJO3>;
}

class POJO2{
field c;
field d;
field e;
field f;
}

class POJO3{
field g;
field h;
field i;
field j;
}

and my file looks like this 

a|b
c|d|e|f
g|h|i|k
a|b
c|d|e|f
g|h|i|k
a|b
c|d|e|f
g|h|i|k
a|b
c|d|e|f
g|h|i|k

which is mapped to fields of POJO's. Can you please help me to achieve this functionality.
